The filename is an empty string when the file save dialog is cancelled, which results in an attempt to open a non-existent file in `ViewerWindow`'s `save()`, `EditorWindow`'s `export()` and `save()`. Since the error isn't caught viscm terminates. This fix checks if the returned string is empty and if it is, no file I/O operation is performed.
